Problem 3 (Merging Dictionaries) Write a function called merge1(d1,d2) that takes two dictionaries as input parameters. This function will create a new dictionary that contains everything from the two input dictionaries and return it. For this problem you can assume that the input dictionaries do not have any keys in common. Create a few dictionaries, print them to screen using the function created above. After this, merge them using the function you wrote and print the result to the terminal. Sample run, >>> d1 = {'A': 100, “c':300} >>> d2 = {'B': 200, 'D':400} >>> d3 = merge1(d1,d2) >>> display(d3) А, 100 В, 200 D, 400 с, зее

Task 01 Write a function that takes a dictionary as a parameter. The dictionary holds student names as keys and their mid-term marks in the python course as values. Your function should get the student name corresponding to the minimum and maximum mark achieved by the student and return it to the function call. Then, finally prints the returned statement after the function call. Sample Input: {'Samin': 25, 'Lily': 28,'Akib': 17,'Salma': 22, 'Imon': 20 } Function Call: function_name({'Samin': 25, 'Lily': 28,'Akib': 17,'Salma': 22, 'Imon': 20 }) Sample Output: Highest scorer: Lily Lowest scorer: Akib Sample Input: {"A":60,"B":30,"P":2, "R":8, "S":33, "T":88} Function Call: function_name({"A":60,"B":30,"P":2, "R":8, "S":33, "T":88}) Sample Output: Highest scorer: T Lowest scorer: P
Dictionary Swap Write a function called dictionary_swap that takes a dictionary as a parameter. It does not modify the original dictionary, but it creates and returns a new one. Keys from the original dictionary become values in the new one, and values become keys. For example, given the inputs below, your program should return the corresponding values. Input to the Function Returns {'one':1, 'two': 2, 'three':3} {1:'one', 2:'two', 3:'three'} {-1:-10, -2:-20, -3:-30} {-10:-1, -20:-2, -30:-3} {} {}
You have been given the following lists of students and their test scores: names=['Joe','tom','bob','sue','sally'] Scores=[10,23,13,18,12]Write a function, makeDictionary , that takes the two lists and returns a dictionary with the names as the keys and the scores as thevalues. Assign the result of makeDictionary to scoreDict .calculate the average of all the scores in scoreDict in python.
Homework Assignment-1Topics: Functions, Dictionary, ImportProblem description: Write a python application to simulate an online clothing system. Thepurpose of this assignment is to gain experience in Python dictionary structure, create basicPython functions and import a module.Design solution: The template file contains a list of clothes item sold, each item in the listcontains the item id, name of the item and the prices. The program will generate an items_dictwhere each key is the item id of the cloth and the values will be a list of item name and priceinformation. A customer will be presented with a main menu with 4 different options: displayall items, add an item to cart, checkout and exit the program. A customer can buy an item byentering the ID of the item. This program implements a dictionary called cart, where each key isthe item id and the values are the list of name, price and quantity that user chooses topurchase. The program keeps repeating by displaying the main menu to…
Python Programming Assignment: Create a dictionary that takes a basketball team's information (that includes team's name and points) as parameter, creates a teams_dict and returns it. Also, create a parameter for write_file parameter that opens current results text file in write mode and writes the dictionary information to file as per format and closes the file.
Problem Statement: The program takes a string and creates a dictionary with key as first character and value as the count of letter in the string and also, sort the dictionary w.r.t the values of count in descending order or sort it based on the key in alphabetical order. Pseudocode: Start of build_dict function An empty dictionary is declared Start of for loop to traverse through the letters of the string If letter is not present as a key in the dictionary The letter is initialized as the key and assign 1 to it ( since initially the count would be 1) Else The value of the letter as key in the dictionary is increased by 1 End of build_dict function Sort the dictionary and assign it back to the same dictionary variable Start of print_dict function Iterate over all the items of the dictionary Print the key and value End of print_dict function Start of main function User must enter a large string and store it in a variable Call the build_dict function with string parameter and return the…
void dict_clear (dict_t* dict); This function clears the dictionary dict, destroying each pair key/value, but does not destroy dict itself (remember that dict was allocated using dict_create, so it will need to be freed at some point, but this is not this function’s job.) This is now the function that frees (destroys) a dictionary: void dict_destroy (dict_t* dict); This operates just as dict_clear, but in addition should free the memory that was allocated during dict_create. After a call to this function, if any other library function receives the pointer dict, the behavior is undefined (most likely, it will crash). This simple function returns the current size of the dictionary: size_t dict_size (const dict_t* dict);
Your program should prompt the user to enter names and salaries from the user. Create a dictionary called information which should be initialized by the values from the two lists that you created above. Your program should pass this dictionary to a function named insights which would calculate and print the names and salaries for each employee. Before printing the salary, your function should multiply the salary by a random number and then print it. [26] For example, name = Employee01, salary = 100 new_salary = salary * random number between 1 and 10

Select from temperatures the column of temperature reading for C d. Select from temperatures the column of temperature reading for A, and B e. Select from temperatures the row for ‘M’ and ‘Afn’ temperature reading
Capital QuizWrite a program that creates a dictionary containing the U.S. states as keys, and their capitals as values. (Use the Internet to get a list of the states and their capitals.) The programshould then randomly quiz the user by displaying the name of a state and asking the userto enter that state’s capital. The program should keep a count of the number of correct andincorrect responses. (As an alternative to the U.S. states, the program can use the names ofcountries and their capitals.) in phyton
